Benefits of technology

[0010]In light of the foregoing, it is desirable to provide a novel and improved image processing apparatus capable of reducing detection omission and erroneous detection of objects to be detected when an object making an entry into the image is detected from image data, an image processing method, and a program.
[0018]According to the embodiments of the present invention described above, detection omission and erroneous detection of objects to be detected can be reduced when an object making an entry into the image is detected from image data.

Problems solved by technology

As a result, because threshold processing is simply performed according to the technology of Japanese Patent Application Laid-Open No. 2008-46769, for example, a horizon portion is determined as a foreign object, leading to erroneous detection of objects.

first embodiment

1. FIRST EMBODIMENT

[Configuration of the Image Processing Apparatus 100]

[0036]First, the configuration of the image processing apparatus 100 according to the first embodiment of the present invention will be described. FIG. 1 is a block diagram showing the image processing apparatus 100 according to the present embodiment.

[0037]The image processing apparatus 100 detects any object (for example, a suspicious-looking object) entering images in a monitoring place by receiving image data from an image pickup camera 10. The image processing apparatus 100 also outputs a binary signal (alarm) to indicate presence / absence of object detection or an image signal after predetermined processing being performed. The output image signal is transmitted to, for example, a large-capacity storage device such as an HDD or another host apparatus via a communication line.

[0038]The image pickup camera 10 (image input means) has, for example, a CCD image pickup device or CMOS image pickup device and outpu...

second embodiment

2. SECOND EMBODIMENT

[0080]Next, the image processing apparatus according to the second embodiment of the present invention will be described. The configuration of the image processing apparatus according to the second embodiment is the same as that of the image processing apparatus according to the first embodiment described using FIG. 1 and thus, a detailed description thereof is omitted.

[0081]The operation of the image processing apparatus according to the present embodiment will be described. FIG. 10 is a flow chart showing the operation of the image processing apparatus 100 according to the present embodiment.

[0082]First, image data is input from the image pickup camera 10 (step S301). Next, the image data is input into the characteristic quantity calculation unit 120 after temporarily being saved in the image saving unit 110. Then, the characteristic quantity calculation unit 120 calculates a characteristic quantity of a whole image of the input image or an area of a portion of...

Abstract

An image processing apparatus is provided which includes a characteristic quantity calculation unit that calculates a characteristic quantity for each pixel of image data from the image data, a tightness determination unit that determines tightness indicating a degree of dispersion of pixels in image data for tightness determination by extracting the pixels having a same characteristic quantity by using the characteristic quantity and generating the image data for tightness determination composed of the pixels having the same characteristic quantity, and a pixel set calculation unit that calculates a set of the pixels from the pixels in the image data for tightness determination in accordance with a determination of the tightness.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image processing apparatus, an image processing method, and a program.[0003]2. Description of the Related Art[0004]To monitor or track an object such as a person or vehicle contained in an image photographed by an image photographing means such as a surveillance camera (ITV camera), it is first necessary for an object in an image to be detected. For example, a system of a monitoring apparatus using a surveillance camera is constructed in which a place to be monitored such as an off-limits area is photographed by the camera, presence / absence of any object contained in the image is detected, and raises an alarm when an object (suspicious object) enters the monitoring place being photographed.[0005]When an object in the image makes an entry, brightness of the object area, that is, a luminance value of the object area in the image changes. Thus, an object can be detected by detecting an a...
